1 wire uart comms
uart protocol for flash programming
01 - soh = start of heading(command sending to chip)
02 - stx = start of text/start transmission(marker for start of reply from chip)
03 - etx = end of text/end transmission(marker for end of reply from chip/end of command data sent to chip)
format of messaging
<stx/soh><length><command/error><checksum><etx>
checksum
Command frame: LEN + COM + all of command information
Data frame: LEN + all of data
